I have been meaning to make a pair of viking shoes for the muse, the inspiration closest to my heart, Miss Sarah L. I also have the good fortune to present these in context, on the feet of the recipient as well! I dare say that they make the photo that much more compelling. In any event, these are out of Goubitz, 9th-10th C., from Vlaardingen. This type of decoration was very common on several examples, and there is a similar piece from Gdansk, Poland. This particular piece even had some remnant threads remaining in the leather.
The extant piece is actually a fragment, but with sufficient detail to render a model for us.
